KCO's semantic annotations are typed, i.e. respond to different aspects of a situation. We distinguish between semantic annotations for multimedia issues, usage contexts, business semantics, trust, access and domain semantics of the content itself. This encompasses initiatives such as proposed by MPEG-7 and Dublin Core and provides a homogenous framework for knowledge exchanges. We consider semantic annotations on the basis of formal ontologies [3]. Ontologies are particularly used for (1) formal evaluation of system specifications [4], (2) semantic filtering and information mining on repositories [2] or (3) automated reasoning [6]. 2. Knowledge Content Objects (KCO) METOKIS can be regarded as an attempt to create an environment for the exchange of information objects that can be consumed by humans as well as machines. This way, these information objects become a (surrogate) means of communication. The analogy would be that the actors are writing a special sort of letters to each other. The inner structure of these letters helps the mac...

...for this task. When machines are involved, surrogates must be found for natural language and for the notion of meaningful statements. We will introduce a "knowledge content object" (KCO) as such a surrogate. Projecting this scenario of knowledge exchanges into a commercial context, firm's ability to create innovative products and service increasingly depends on its knowledge exchange capabilities within the organisation and beyond [8]. With increased innovation cycles and decreased product cycles, firms are forced to leverage internal and external knowledge in efficient and effective fashions [1, 5]. A firm is challenged to produce needed knowledge assets, to use it internally in multiple ways, to leverage them as products by knowledge markets for reasons of branding, customer relationship maintenance or direct sales and to distribute them over an increasing variety of channels and devices. Hence, knowledge becomes a scarce and valuable resource that calls for economic steering, control, protection and exploitation within the boundaries of an organisation but more importantly also between organisations and amongst individuals [2, 5]. Within this context, information technology primarily ...

A firm is challenged to produce needed knowledge assets, to use it internally in multiple ways, to leverage them as products by knowledge markets for reasons of branding, customer relationship maintenance or direct sales and to distribute them over an increasing variety of channels and devices. Hence, knowledge becomes a scarce and valuable resource that calls for economic steering, control, protection and exploitation within the boundaries of an organisation but more importantly also between organisations and amongst individuals [2, 5]. Within this context, information technology primarily acts as a transfer medium that allows to store and to transmit knowledge assets engrained into data structures independent of time and space [7]. As a result, huge networks of heterogeneous information and data networks have been erected by organisations and individuals. Thereby an important driver for web presences and intranets of commercial firms has been to follow their competitors. In general users require that information systems deliver dedicated information to application domains in a ready-to-use and ready-to-execute fashion. Thi...
